Description

[0001] This invention, as stated in the enunciation of the description, relates to a device for checking condensers and coils in motor vehicles.

[0002] The object of the invention is to introduce into the market an electric device with a special arrangement of its circuits, which is substantially divided in two assembled portions, the first of which is employed to check the condition of the condensers, verifying the leakages existing in the same, while the second is used to check the ionization state of the coils having the function of transforming the battery current in high-voltage current to produce an effective spark in the sparking plugs of the engine.

[0003] To this end, the leakage checking circuit used to check the condensers, is characterized in that it comprises a socket for the 220 V alternating current in the positive pole of which a switch has been arranged and then a resistor, extending in two derivations into which corresponding condensers are connected in parallel to increase the capacity of the circuit, needed to transform the alternating current in direct current during its passage through the recti- fier diodes that are arranged in continuation.

[0004] The current goes from one of the condensers to an outlet branching to a contactor through one of the poles to be checked, while the same conductor extends and passes through one of said rectifiers, continuing to connect with the negative pole of the socket and to go through the second rectifier diode, adding to the outlet of the second condenser and editing as rectified direct current by a branch till the other contactor which is connected to the other pole of the condenser to be checked, in this outlet pole a 220 V neon lamp being arranged.

[0005] All this is arranged in such a way that when the checking of the vehicle condenser is carried out, the same is charged with current till its full capacity and no current shall pass through it.

[0006] Each tine that the neon lamp lights, this means a leakage from the checked condenser, being allowed three leakages per minute to know that the condenser can be employed.

[0007] On the other hand the checking circuit for the condensers comprises a short-circuited connection, actuated by means of a push button and apt to discharge the system and the checked condenser, and throuch the actuation of which the switch of the socket in the circuit will be opened.

[0008] The second portion of the circuit, that will be identified as controlled derivation circuit, is employed to verify the condition of the coils of the vehicles and is characterized in that in the outlet positive pole directly connectable with the coils, it comprises a wound potentiometer with a derivation to a revolution indicator and the othe derivation to the short-circuit push-button, whose outlet conductor is grounded to the vehicle, and further from the revolution indicator exit two couplings, one for the positive terminal of the battery and the second for the negative one.

[0009] All this is arranged in such a way that the checking is carried out starting the engine stabilizing its running to the optimum rpm and passing the sliding contact of the potentiometer point by point, from minus to plus, causing in each point, by means of the push-button, a short-circuit that in turn tends to cause the reduction of the revolutions of the engine against the performance of the coil, so that the ionization tension of the latter is measured to supply the ignition circuit of the engine and the reserve capacity it contains.

[0010] In order to assist the understanding of the idea set forth, the present description is accompanied, as an integrating part of the same, by a plan in which the object of the invention has been illustrated, being it intended that the diagramatic illustra- tionshould not represent a limitation of the specific features of the present application.

[0011] The sole figure represents a diagram of the checking circuit for condensers and coils. In this it can be noted that the circuit is divided in two portions, the first portion acting as a leakage verifier of the condenser of the vehicle, while the second portion of the circuit is the controlled derivation to check the condition of the coil of the vehicle.

[0012] The leakage checking device due to verify the condition of the condensers of the vehicle, comprises a 220 V socket having a positive pole (1) and a negative pole (2):

In the positive pole a switch (3) has been arranged and in continuation a resistor (4).

[0013] The circuit comprises two derivations (5) and (6), in which two condenser in parallel (7) and (8) have been provided, in order to increase the capacity of the circuit.

[0014] This increase of the circuit capacity is necessary to transform the alternating current in direct current during its passage through the rectifier diodes (9) and (10) which are connected as a continuation.

[0015] All-this is arranged in such a way that the current goes from the condenser (8) to a derivation (11) with exit to a contactor (12) at one of the poles of the condenser of the vehicle to be checked.

[0016] The same conductor of the derivation (6) extends and goes through said rectifier (9) till it connects to the negative pole (13) of the socket and goes through the second diode (10) adding to the outlet of the second condenser (7) and exiting as a rectified direct current through a derivation (14) till the other contactor (15) which is connected to the other pole of the condenser to be checked.

[0017] To this exit pole a 220 V neon lamp (16) is connected, which signals the leakages existing in the checked condenser.

[0018] What happens is that during the checking of the vehicle condenser, this is charged by the current as much as allowed by its capacity and no current shall pass through it.

[0019] When there is a leakage in the checked condenser, the neon lamp will signal it, only three leakages per minute being allowed to show that the checked condenser is in a good condition for its use.

[0020] On the other hand, the checking circuit for the condensers comprises a short-circuited connection (17) actuated by means of a push-button (13).

[0021] Actuating the push-button of the short-circuited connection, the discharge of the system and of the checked condenser will be produced, but previously by the same the supply switch (3) of the circuit will be opened.

[0022] The second portion of the circuit or controlled derivation circuit, is employed to check the coils of the vehicles.

[0023] To this end the exit positive pole of the circuit (15) is connected.to the coil of the vehicle directly and to this pole a wound potentiometer (19) is connected,which is only a resistore adjustable as desired.

[0024] Said potentiometer presents a derivation (20) to a revolution indicator (21) and another derivation which pertains to the short-circuits (17) actuatable by the push-button (18), whose connection or exit pole (12) is grounded to the vehicle.

[0025] Two couplings (22) and (23), respectively, exit from the revolution indicator (21), for the connection with the positive and negative terminals of the vehicle battery.

[0026] All this is arranged in such a way that the check of the vehicle coil is carried out starting the engine, which stabilizes to an optimum rpm.

[0027] When the speed of the engine is stabilized, the potentiometer (19) is actuated displacing its sliding contact from ninus to plus, causing in every point a short-circuit by means of the push-button (18).

[0028] Said short-circuit tends in turn to cause a redution of the revolutions of the engine, against the performance of the coil, so that the ionization tension of the same is measured, which will state if it is in a good condition, in order to transform the battery current in high voltage current to produce an effective spark in the sparking plugs of the engine.

[0029] Having described the present invention, it must be noted that the details of the invention can be modified, that is they are subject to minor variations always based on the essential principles of this invention, which substantially are those stated in the paragraphs of the above description.
